Natural Features & Ecosystems
The primary resource of Jewel Cave National Monument is the cave itself. Jewel Cave is a unique world of sparkling calcite crystals, delicate strands of gypsum, and other spectacular cave formations. It contains large rooms strewn with boulders, tight crawlways, and dark fissures leading into the unknown.
Did You Know?
Jewel Cave has only one natural entrance. Although the cave is more than 160 miles long, it lies beneath just 3 square miles of land area.
